'Be it known that I, FREDERICK WILLIAM VIGKERY, a subject of the King ofGreat Britain, residing at 13 St. Anns Villas, Not-.

ting Hill, London, England, have invented.

certain new and useful Improvements in or Connected with Paner-FeedingMachinesfor.

Printing or Like 'lvlbgchines, of which the following is aspecification.

The object of my invention. is to construct an appliance capableo'fbeing connected to any sheet rinting machines, whereby the top sheet05 the pile of paper is positively re v leased from contact with itsneighboring sheet before leavin the pile to be fed into the machine andis hept from contact during the feed.

My invention is illustrated in the annexed drawings Figure 1 being aside elevation of a paper feeding machine with one side frame and anumber of the operative parts for actuatingthe air box'removed; Fig. 2is a plan view of Fig. 1 Fig. 3 is a fragmentary view partly in sectionof the automatic cut-0H in" z 5 the air supply pipe; Fig. 4 is a topview thereof; Fig. 5 1s a side view of a portion of a machine on anenlarged scale showing the mech: anism for actuating .the movable airbox; Fig. 6 is a similar view from the other side of the machine andshowing the gearing for operating the movable air box; Fig. 7 is an'enlarged view ofthe arms situated over the pile of paper and their meansof suspension; Fig.

In the drawings a designates the usual frame of a printing machine, andb, b are standards attached toor forming part of said frame, thesestandards carrying a rising and falling feed table a supported by bars dslid" ing vertically in the uprights of the standards b, I). Thesefeatures torm no part of my present invention, and therefore need not befurther explained herein. For the purpose of my invention I make ahollow box or pipe 6, or the like, and perforate same along one side oredge as'at This box or pipe 6 is in connection by a tube 9 with a fan,pump or like device actuated from the printing machine, or a separateappliance.

The perforated box 6 is mounted on rocking arms h, h which are fixed onan oscillating Specification of Letters Patent. Application filedDecember 11,1903. Serial n. 184,822.

In Fig. 1 said box ais shown at i lowest posit on, and, ccnsegu'entiy, the 'a supply isnearly (closed.- The. aeriotate boxe can be fitted on either or allsir'l'es' of the pile of paper asfolrcinnstances require, and f moves inunison with the feed, that-isto say,

Theroller is moved around the axle p and gust before it commences to reachthe pile of paper the air box e has risen and the blast 01' air hasimpinged against the edges of the sheets and passeda1r between them soas to separate or form a film of air between said sheets, the latter being held by the bars q.

Theroller 9 acts on the sheet some little distance from its edge so thatthe sheet is grlipped from the pomt of contact with the re er and. theedge of the air box, the front of the sheet being) sufficiently far fromthe roller to be grip ed the rollers 27, and the band 1: before t erollbr 9' leaves the air box; The rollers j are frictionall held intheir bearings and .in moving aroun get a slight revolution by actionfresh surface for action on the next sheet. It will be ap arent that thesprin controlled knuckleointed feed rollers 9' when in ration move in adirection over the pile 0 paper and arecaused t'o gri thetto sheet asthe. jets of air lift said top s eet an force the same against the saidfeed rollers 7', cansing the sheet to adhere to the rollers and at thesame time the film of air enters from the air box 0} between the topsheet and its neig sheet,-'and in consequence the said top sheet can bemoved by continued 0 eration of the rollersg', which are moved by t eshaft p without in any we drawing the neighbormg sheet with it, an asthe operation of the machine is continued a successive feed of 1e sheetsis insured.

The chain 1 is in gear with a wheel not shown on the machine, andactuated either directly or indirectly from the prime mover, this chain1 meshing with a pinion 2 on a shaft 3 journaled in bearings 4 on thestand ards b. On one end of the shaft 3 is mounted two chain wheels 5and 6, the wheels 5 gearing by a chain 7 with a sprocket wheel 8revolving on a fixed shaft 9. This Wheel 8 is in connection with asprocket wheel 10 which meshes with a pinion 11 on the shaft p for ocrating the same. On the other end of the s aft p is affixed a cam 12which acts against a roller 13 on, a lever 14 which is pivoted on theshaft 7; which carries the arms it having the air box 6 so that the airbox 6 is operated. 'On the shaft 1) is mounted another cam 15 whichoperates a lever 16, this being pivoted at 17 to the standard-handcarrying at its free end a rod 18, having at its lower end a nose 19 forengaging a ratchet wheel 20,. which. 0 eratesa, chain 21 attached to theguides supporting the table 0 so that each time the cam 15 operates thelever 16, the rod 18 will turn the wheel 20 one tooth.

The wheel 6 is connected by endless chain 23 with a pinion 24 on theroller 25 which carries the endless band v.
